Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the invention and practice it.
Examples
The invention discloses a soft starter power connector, which replaces the existing soft starter power wire and is used as an electric connecting piece between the soft starter and a three-phase power supply, and is shown by referring to figures 1-5, and comprises an insulating seat 2 and a connector main body 4;
the connector bodies 4 have three groups connected to three-phase power sources, respectively, and the three groups of connector bodies 4 have the same structure, and as shown in fig. 3, each of the connector bodies 4 has a conductive bar 41, and a power source connection terminal 42 and a plurality of soft starter connection terminals 43 integrally formed on the conductive bar 47. The number of the soft starter connecting terminals 43 formed on the conductive bars 41 is determined according to the number of soft starters, namely, the number of the soft starter connecting terminals 43 formed on the single conductive bar 41 is the same as the number of soft starters configured in the control cabinet, and each group of three soft starter connecting terminals 43 correspondingly configured by the connector main body 4 with the same three groups of structures are respectively connected and used corresponding to three-phase power connecting terminals of one soft starter. The power supply connection terminals 42 and the soft starter connection terminals 43 are arranged in this order along the length extending direction of the connector body 4.
As shown in fig. 4 to 5, three sets of insulation grooves 21 are sequentially provided in the insulation base 2, the three sets of connector bodies 4 are respectively inserted into the three sets of insulation grooves 21, and the power connection terminals 42 and the soft starter connection terminals 43 of the three sets of connector bodies 4 extend to the outside of the insulation grooves 21; the free ends of the power connection terminals 42 of the three groups of connector bodies 4 extending outwards are respectively connected with three-phase output terminals of a three-phase power supply in a conductive manner; the free ends of the soft starter connection terminals 43 of the three connector main bodies 4 extending outward are respectively electrically connected to the three phase connection terminals of the soft starter. That is: each group of connector main body 4 is provided with a power supply connecting terminal, and the three power supply connecting terminals on the three groups of connector main bodies 4 are respectively and electrically connected with three-phase output terminals of a three-phase power supply. Each group of connector main body 4 is provided with nine soft starter connecting terminals 43, twenty-seven (9*3 =27) of the three groups of connector main bodies 4 are divided into nine soft starter connecting terminal groups, each group comprises three soft starter connecting terminals 43 respectively positioned on the three groups of connector main bodies 4, and the three soft starter connecting terminals 43 of each soft starter connecting terminal group are respectively and electrically connected with three phase connection electric terminals of one soft starter. In the technical scheme of the embodiment, the conductive bars 47, the power connection terminal 42 and the plurality of soft starter connection terminals 43 are integrally formed conductors, when the power connection terminal 42 is electrically connected with the three-phase power supply, the soft starter connection terminal 43 is electrically connected with the power connection terminal of the soft starter, so that the conductive connection between the soft starter and the three-phase power supply is realized, and the soft starter receives the power supply of the three-phase power supply. Therefore, one power connector can enable nine soft starters to be synchronously connected with a three-phase power supply. Of course, according to the actual use requirement, one power connector can also be matched with the power connection of a plurality of soft starters, and the number of the soft starter connecting terminals 43 does not limit the application. The power connector is more suitable for being used in the case of configuring a plurality of soft starters in a circuit control structure.
Specifically, as shown in fig. 4 to 5, the insulating base 2 has a soft structure, and in the present embodiment, it is preferable to mold the insulating base 2 from rubber, and to use the insulation and plasticity of the rubber itself. The insulating base 2 has an upwardly open built-in cavity 22, a partition rib 23 is provided in the built-in cavity 22, the partition rib 23 partitions the built-in cavity 22 into three groups of insulating grooves 21 electrically isolated from each other, and the partition rib 23 is integrally formed with the body of the insulating base 2. The three groups of connector bodies 4 are respectively inserted into the three groups of insulation grooves 21, and the separation ribs 23 isolate the electrical performance among the connector bodies 4, so that the problem of short circuit among the connector bodies 4 is avoided. The three groups of connector bodies 4 are respectively inserted into the three groups of insulation grooves 21 to finish the installation of the power connector, so that the installation is very convenient and quick, and the fool-proof effect of preventing misconnection is achieved to a certain extent.
As shown in fig. 5, the open design of the built-in cavity 22 of the insulating base 2 can facilitate the insertion of the connector body 4, but another safety hazard is brought, namely, the soft starter connection terminal 43 and the power connection terminal 42 at the open position have the problem of short circuit after being overlapped by the external conductor. In order to solve this problem, in the solution of the present embodiment, an end cover 24 is horizontally folded at the opening end of the recessed cavity 22 of the insulating base 2, an insertion gap 25 is provided between the end cover 24 and the opening end of the recessed cavity 22, and the connector body 4 is inserted into the insulating groove 21 from the insertion gap 25. The horizontally folded end cap 24 can avoid shorting at the open end. On the other hand, the power supply connection terminal 42 and the soft starter connection terminal 43 are formed by being folded horizontally outward. The turning direction of the power supply connection terminal 42 and the soft starter connection terminal 43 is the same as the turning direction of the end cover 24, so that the three sets of connector bodies 4 can be smoothly inserted into the three sets of insulation grooves 21 with the narrow insertion gap 25.
The soft starter connection terminal 43 and the power connection terminal 42 are each provided with a conductive connection portion 44 at a free end extending outward. The starter connection terminal 43 and the power supply connection terminal 42 are electrically connected to the three-phase output terminal of the three-phase power supply and the three-phase connection electric terminal of the soft starter, respectively, through respective electrically conductive connection portions 44.
The end of the insulation groove 21 in the length extending direction is provided with a limiting part 26, and the limiting parts 26 of the three groups of insulation grooves 21 are staggered in sequence. After the connector main body 4 is inserted into the insulation groove 21, the end parts of the connector main body are abutted against the limiting parts 26, and the limiting parts 26 of the three groups of the insulation grooves 21 are sequentially staggered, so that the soft starter connecting terminals 43 on the adjacent connector main bodies 4 are sequentially staggered after the three groups of the connector main bodies 4 with the same structure are respectively inserted into the insulation groove 21, and the three adjacent soft starter connecting terminals 43 of the three groups of the connector main bodies 4 are ensured not to be short-circuited, and the soft starter connecting terminals 43 between the two adjacent groups of the connector main bodies 4 are ensured not to be short-circuited.
The above-described embodiments are merely preferred embodiments for fully explaining the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present invention, and are intended to be within the scope of the present invention.
